Types of nut units

The range is enlarged by the offer of non-standard connecting
dimensions of nuts. Both nuts and screws can be manufactured according
to the requirements of the customer.

The profile of the thread is
produced in compliance with the standards ISO 2901- 77, ISO 2902-77, ISO 2903-77 and ISO 2904-77 or with the corresponding ČSN 01 4050.

Shafts are usually made from steel grade 54SiCr6 and CF53. The standard performance of the shaft is without heat treatment.

The
nuts can be made from cast iron with grade 422425, from tin bronze Cu –
Sn12, or from plated steel (steel shell, plated with bronze Cu – Sn12).
Technical consultation and delivery of the plated steel material is
needed in the case of plated nut design.
